It, isa purposeofthe present inventionto provide, in the construction of a cupola, a L sliding closure for the purpose of closing an closure may bev operated to an open position of the roof. -With this in view,

opening means in proximity to the floor of the garage, stable, barn, or'the like, whereby the from a location remote from the cupola. V In the construction of most; cupolas',rthe

roofs'either consist of opposite inclined por tions with 'a roof ridge or are of polygonal sha e and the ventilating openings closely approximate the inclined or polygonal parts it is another purpose to providea sliding closure of a flexible; construction, preferably. flexible sheet metal, so that when the closure is raised to an open position, the clo'surewill conform to the shape of the roof, there being suflicient gravity means mountedonthe closure to'return the closureto its closed,

position when the operatingmeans is released,"the gravity means being overcome any frictionthat may be present betweenthe closure and the guides .or beg tween the closure and the roof when'the closure conforms to the shape of'the roof.

Still another purpose is to .provide a flange at the bottom of the closure to overlap and extend on .theouts'ide ofthe wall ofthe cupola when the, closure is lowered."

' The mventlon comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed. 1 v

Referring to the drawings, 1' designates a I cupola which may be constructed of any suitable material, such as wood or metal, and

win the construction of metal garages, ity is preferable to use sheet metalfor the cupola.

It is obvious that the cupola maybe any-size or shape and it is to be noted that the closure is not limited to application to cupolas in the wall of the cupola, with.

suificient; to I f'stables, barns or like structures.

JOPPOSltG walls of the'cupola have ventilating openings 2 which may or may not of ga ra'ges may b e 'applied to those on haveutransverse slats (not shown). cAdjacent'the vertical edgesof each opening are gu1d'es3' preferably of sheet metal, and mounted in the g'UldBSJS a closure 4:. The

lower portion of the closure terminates in an outwardlyanddownwardlyturned flange 5 which extends outwardly and overlies the lower edge of the ventilating opening. The

closure 4 is constructed of light sheet metal,

relatively 1 flexible, so that whenf the closure is raised, it will conformto the shape of the v roof of the cupola. ,1

. 'Attachedto the which is provided withan eye 6, is a rope or cable 7 which passesthrough a guideloop upper end of each closure,

8and engages with a pulley 9 (which is susj pended at 10 from the remoteridge portion of the roof), the cable: or rope terminating floor of the garage, stable or barn. purpose of providing the rope, so terminat- "sameand pull thereon so as to raise the closure'and due to the closure being relatively flexible, it conforms to the shape ofthe roof when the closure is in a" raisedposition;

The closure, however, is provided with a or any friction between the closure and the roofof the cupola, so that when the cable orrope. is released by the operator, such gravity l means will act to return the closure noted that the closure has means, Jsuch as at its other end in close proximity to the f The" to its normal lowered position. It will be ing, is to enable'an operato to grasp he I:

weight ll which issufiicient to overcome any 7 undue friction of-the closure 1n its guldes arms 12,"so tliatthe number of weights may be increased or decreased; In otheriwords, 1

one er more weights maybe carried by the closure'to nsure "overcom ng any undue fr1ct'lon. w a I is claimed is:

the wall of the cupola, with guides adjacent the vertical edges of the opening,

In a closure structure for a cupola, the combination with'a ventilatlng opening 1n 7 ice 7 The'invention having been set forth, what sure, and gravity means carried by the 010- sure sufficient to overcome any undue friotion for returning the closure to a lowered position, the'lower edge of the closure ter;

:a ventilating opening provided with guides 10 adjacent its vertical edges, of a, closure mounted in said guides. and haying a'flange at its lower edge extending outwardly and v voverlying the lower edge of said opening,

said closure being' 'gravity impelled to closed position, and means actuable from a' remote point for raising'said' olosure to open position. i e
